' IMPROVEMENT IN MACHINES FOFI FEEDING WIRE T0 HAMMER-DIES.

Specification forming part of Letters Patent No. 141,922, dated August19, 1873 application filed March 2l, 1873.

To all whom it may concern:

Be it known that I, WILLIAM II. DAYTON, of Wolcottville, in the countyof Litchfield and State of Connecticut, have invented an Improvement inMachines for Feeding Blanks to Reducing-Dies, of which the following isa specification:

Machines have been made for reducing wire to form needles, and formaking other articles, by lateral compression upon a wire or rod. Suchmachinery may be seen in the patent granted to Hopson and Brooks,February 26, 1867, No. 62,336, and a reference is hereby made to thesame as showing a reducing-machine with which the present improvementscan be used.; and my invention relates to4 devices for supplying wiresor blanks, and presenting the same, one at a time, to the reducingmechanism.

I make use of a hopper to which a risingand-falling motion is given atthe proper time to bring the blanks into line with a pair of jaws thatseize the blank and draw it out of the hopper, then the hopper is liftedoutof the way, and thev jaws move the blank forward into the reducingmechanism. There is a yielding device between the jaw-moving mechanismand the jaws, so that the blank will not be moved positively while thecompressing mechanism is reducing the same, but the feeding motion willoperate between the respective reductions.

In the drawing, Figure lis a plan of the feeding mechanism. Fig. 2 is avertical longitudinal section of the same, and Fig. 3 is an endelevation.

The bed a is mounted in ways b, and receives a movement endwise by meansof the cam c upon ashaft, d, that is rotated by the wheel e andworm-pinionf, or other convenient mechanism. The jaws g g are attachedby the screws 2 to a plate, h, above the bed a; and this plate Vh isadjustable by slots and screws 3 and 4, so that .the blank 5 between thejaws g will be exactly in line with the compressing and reducing dies7c, which are of the general character shown in aforesaid patent, andact 'by compression to reduce and elongate the blank 5 for asewing-machine needle or other article. The spring 6 acts to open thejaws g, and the wedge 7 acts to close them and hold the blank 5. Saidwed'ge 7 is made to slide longitudinally in a case upon the plate h, andis operated upon at the proper'time by the cam m upon the shaft d,acting through the slide a, lever a', rack p, pinion 9, shaft m2, andcam m3; and I remark that the cam m is circular in a portion of itsperiphery, so as to hold the blank during the reducing operation. Thelever a is slotted, so as to allow it to move forward with the bed a asthe blank is moved intothe reducing-dies lo. At the proper time the camm allows the jaws to open and drop the blank or reduced article. Y

In order to allow of a slight pause in the forward movement of the blankas it is pressed into the die, thereby not attempting to move the blankat the moment the reducing-dies are operating, I introduce a block ofrubber or other yielding material at 11, that allows of this pause, andthen moves the blank rapidly forward between the compressing-dies themoment they open.

It is often necessary in reducing the blank considerably to draw theblank out slightly periodically, so that the oil which drops upon theblank may spread upon the part that is being reduced; to effect thisthere are depressions 13 in the cam c at such places as may benecessary. The portion l5 of said cam is gradual, snail, or increasingvolute. To move the blank into the dies, the portion 16 allows Y.

the spring or weight r to draw back the bed a and jaws g; the portion 17moves the jaws forward to grasp a blank in the hopper next described thepart 18 allows the bed to draw back to withdraw the blank from thehopper, and thepart I9 moves the bed a and blank rapidly forward t bringthe blank into proximity to the reducing-dies. The hopper s is of a sizeto receive the wires or blanks, and it is made with a strap or bottom,20, that prevents the blanks dropping out, but gives room for the jawsto grasp the lowest blank in the hopper. After the jaws have drawn outthis blank the hopper is raised by the cam t, arm t', shaft c, and levera, so as to betont of the way of the jaws g. At the time the jaws g openand drop the reduced blank, needle, or article, the cam tallows thespring` 23 to draw down the hopper for the next blank to be taken. Thepost w arrests the downward movement of the hopper by the screw 24resting thereupon, and this allows for the hopper being adjustedvertically to position for the jaws, and the hopper s being attached bythe screw 25 to the arm u allows for the same to be moved laterally intoline with saidjaws.

It will be evident that the movement given to the hopper lessens theliability of the blanks to stick or catch therein, because they areconstantly shaken.

The jaws may be moved forward by a screw, if desired, in place of a cam,and the arrangement of the actuating cams and levers might be varied tosuit the other parts ofthe machinery.

I claim as my inventionl. A pair of jaws opened and closed to grasp ablank, and moved back and forth in line of the blank, in combinationwith the rubber sprin g ll or other yielding material interposed betweenthe jaws and their actuating mechanism, substantially as set forth.

2. A hopper to which a rising-and-falling motion is communicated, incombination with a pair of jaws that are reoiprocated to draw the blankout of the hopper, and then carry the same forward into thereducing-dies, substantially as set forth.

3. The cam t, arm t', shaft c, arm u, adjusting-screw 24, and stop w, incombination with the hopper s and attaching-screw 25, for moving andadjusting such hopper, as set forth.

4. The wedge 7 and its cam m, pinion 9, rack p, slotted lever u', andcam m3, in combination with the jaws g, for closing such jaws andholding the blank during the movement of such jaws, substantially as setforth.

Signed by me this 14th day of March, A. D. 1873.
